Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground reference pin for the device (0V return). |+| 2 | FB | input | Feedback input for output voltage regulation. An external resistor divider from VOUT sets the output; internal reference is 1.25V. VOUT = 1.25 * (1 + R2/R1). Absolute max 7V. |+| 3 | SW | output | Power switch output node (drain of internal PMOS). Connects to the external inductor and freewheeling Schottky diode. Also connected internally to the exposed metal tab. Peak switch current up to 12A (14A typ limit). |+| 4 | VC | passive | Internal voltage regulator bypass pin. Connect a 1uF ceramic capacitor between VIN and VC. |+| 5 | VIN | power_in | Power supply input, DC 8V to 36V recommended operating range (40V absolute max). Requires a bulk electrolytic capacitor to GND (e.g. 470uF/50V) to reduce input noise. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI |+| Package | TO-220-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XL4016E1E1`++## CAD (KiCad official)++- Symbol: `XL4016E1`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XLSEMI datasheet](docs/xl4016e1-datasheet.pdf) (10 pp, sha256 `af9fe1b7a2838fe9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
